REFINED UNCERTAINTY BUDGET FOR REFERENCE TORQUE CALIBRATION FACILITIES

Andreas Brüge

Abstract

Contributions of uncertainty budgets suitable for special applications of reference torque calibration facilities are calculated with a Monte Carlo method implemented in a spreadsheet software application. The simulations were combined with measurements of parameters with a high number of observations and compared with usual simplified uncertainty estimations for examples of uncertainty contributions concerning traceability of voltage ratio, noise, resolution and position effect. The results are more differentiated and detailed than usual GUM estimations and provide deeper understanding about uncertainty contributions than with GUM methods exclusively. New proposals for the uncertainty estimation of the examined contributions are offered.
